Variables

var (
	// Doc is the default 'document' object.  This should be used for regular
	// code. See NewDocForTesting() for a Document object that can be used in
	// unit tests.
	Doc = js.Global.Get("document")
)

Functions

func DefaultQueryString

func DefaultQueryString() string

DefaultQueryString returns the query string used to request the current document. This is likely not available during unit tests, but is available in normal operation.

Types

type DOM

type DOM struct {
	// contains filtered or unexported fields
}

DOM provides an API for interacting with the DOM for a Document.

func New

func New(doc *js.Object) *DOM

New returns a DOM instance for interacting with the specified Document object.

func (*DOM) AppendChild

func (d *DOM) AppendChild(parent, child *js.Object, populate func(child *js.Object))

AppendChild adds the child object. If non-nil, the populate() function is invoked on the child to initialize it.

func (*DOM) Close

func (d *DOM) Close(o *js.Object)

Close closes the specified dialog.

func (*DOM) DoClick

func (d *DOM) DoClick(o *js.Object)

DoClick simulates a click. Any callback registered by OnClick() will be invoked.

func (*DOM) DoDOMContentLoaded

func (d *DOM) DoDOMContentLoaded()

DoDOMContentLoaded simulates the DOMContentLoaded event. Any callback registered by OnDOMContentLoaded() will be invoked.

func (*DOM) GetElement

func (d *DOM) GetElement(id string) *js.Object

GetElement returns the element with the specified ID.

func (*DOM) GetElementsByTag

func (d *DOM) GetElementsByTag(tag string) []*js.Object

GetElementsByTag returns the elements with the speciied tag.

func (*DOM) NewElement

func (d *DOM) NewElement(tag string) *js.Object

NewElement returns a new element with the specified tag (e.g., 'tr', 'td').

func (*DOM) NewText

func (d *DOM) NewText(text string) *js.Object

NewText returns a new text element with the specified text.

func (*DOM) OnClick

func (d *DOM) OnClick(o *js.Object, callback func())

OnClick registers a callback to be invoked when the specified object is clicked.

func (*DOM) OnDOMContentLoaded

func (d *DOM) OnDOMContentLoaded(callback func())

OnDOMContentLoaded registers a callback to be invoked when the DOM has finished loading.

func (*DOM) RemoveChildren

func (d *DOM) RemoveChildren(p *js.Object)

RemoveChildren removes all children of the specified node.

func (*DOM) RemoveEventListeners

func (d *DOM) RemoveEventListeners(o *js.Object) *js.Object

RemoveEventListeners removes all event listeners from an object and its children. This is accomplished by cloning the object, which has the side effect of *not* cloning the event listeners. The newly-created object is returned.

func (*DOM) SetValue

func (d *DOM) SetValue(o *js.Object, value string)

SetValue sets the of the object.

func (*DOM) ShowModal

func (d *DOM) ShowModal(o *js.Object)

ShowModal shows the specified dialog as a modal dialog.

func (*DOM) TextContent

func (d *DOM) TextContent(o *js.Object) string

TextContent returns the text content of the specified object (and its children).

func (*DOM) Value

func (d *DOM) Value(o *js.Object) string

Value returns the value of an object as a string.

type URLSearchParams

type URLSearchParams struct {
	// contains filtered or unexported fields
}

URLSearchParams is a thin wrapper around the URLSearchParams API. See https://url.spec.whatwg.org/#urlsearchparams.

func NewURLSearchParams

func NewURLSearchParams(queryString string) *URLSearchParams

NewURLSearchParams returns a URLSearchParams for the specified query string.

func (*URLSearchParams) Has

func (u *URLSearchParams) Has(param string) bool

Has indicates if the query string contains the specified parameter.
